The Queen's vintage Rolls Royce is up for auction

After more than six decades, Queen Elizabeth II is parting with her beloved Rolls Royce.

According to The Telegraph, the 1950 Rolls-Royce Phantom IV State Landaulette will be sold at auction for around £2 million (approximately $3.5 million AUD).

The extremely rare model was made to be used by the British royal family and heads of state and is a particular favourite of the Queen and her husband, Prince Philip.

The royal couple has been seen at countless events over the years arriving in the luxury car.

In fact, the Rolls Royce Phantom fleet has been a preferred mode of transport for the royal household since the late 1950s.

More recently, the model gained international media attention when a Phantom IV, similar to the Queen's personal car, transported Meghan Markle and her mother Doria Ragland to the Royal Wedding at Windsor Castle on May 19.

The vintage Rolls Royce used to carry the Duchess of Sussex to her future husband, Prince Harry, was one of just 18 models created.

Her majesty's second-hand car will reportedly be sold as part of a collection of royal cars, including a 1960 Rolls-Royce Phantom V "High Roof" State Limousine that was also frequently used by the Queen and Duke of Edinburgh, a 1979 Rolls-Royce Phantom VI Limousine that was loaned to the Royal family, and a 1985 Rolls-Royce "Centenary" Silver Spur Saloon that Princess Diana occasionally rode in.

The September 8 auction will be hosted by British auction house Bonhams, and will be part of a three-day annual motoring festival The Goodwood Revival Sale.
